### Describe the bug Hash join dynamic filter pushdown is unsafe when the join uses `NullEquality::NullEqualsNull`, such as joins with `IS NOT DISTINCT FROM` or set operations like `INTERSECT`. Dynamic filters derived from the build side can be pushed into the probe-side input, where they will not be evaluated with the required null-equal join semantics. i.e., NULL-containing rows might be pruned somewhere within the probe-side plan and won't make it to the join operator. ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
